Wnt signaling pathway

The Wnt signaling pathways are a group of signal transduction pathways made of proteins that pass signals into a cell through cell surface receptors. Three Wnt signaling pathways have been characterized: the canonical Wnt pathway, the noncanonical planar cell polarity pathway and the noncanonical Wnt/calcium pathway. All three pathways are activated by binding a Wnt-protein ligand to a Frizzled family receptor, which passes the biological signal to the protein dishevelled inside the cell. The canonical Wnt pathway leads to regulation of gene transcription. The noncanonical planar cell polarity pathway regulates the cytoskeleton that is responsible for the shape of the cell. The noncanonical Wnt/calcium pathway regulates calcium inside the cell. Wnt signaling pathways use either nearby cell-cell communication (paracrine) or same-cell communication (autocrine). They are highly evolutionarily conserved in animals, which means they are similar across animal species from fruit flies to humans.

Signal transduction

Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.

History

In 1970, Martin Rodbell examined the effects of glucagon on a rat's liver cell membrane receptor. He noted that guanosine triphosphate disassociated glucagon from this receptor and stimulated the G-protein, which strongly influenced the cell's metabolism. Thus, he deduced that the G-protein is a transducer that accepts glucagon molecules and affects the cell. For this, he shared the 1994 Nobel Prize in Physiology or Medicine with Alfred G. Gilman.

The earliest MEDLINE entry for "signal transduction" dates from 1972. Some early articles used the terms signal transmission and sensory transduction. In 2007, a total of 48,377 scientific papers—including 11,211 review papers—were published on the subject. The term first appeared in a paper's title in 1979. Widespread use of the term has been traced to a 1980 review article by Rodbell: Research papers focusing on signal transduction first appeared in large numbers in the late 1980s and early 1990s.

    What are common cell signaling pathways? To make a multicellular organism, cells must be able to communicate with one another, and to do it cells often send out tiny chemical signals that act on the receptors on other cells. Signals can be classified according to the distance between the signaling cell and the target cell. Find our full video library only on Osmosis: http://osms.it/more.

What are common cell signaling pathways? To make a multicellular organism, cells must be able to communicate with one another, and to do it cells often send out tiny chemical signals that act on the receptors on other cells. Signals can be classified according to the distance between the signaling cell and the target cell. Find our full video library only on Osmosis: http://osms.it/more.

Now that we know some things about immune cell structure and function, we need to start understanding how these cells interact on the molecular level, and how signals are translated into cellular response. This means looking at receptor-ligand interactions. What is signal transduction?What are kinases? What are GTPases? What are G-proteins? We need to know about these important cellular components if we are going to understand the immune system, so let's take a closer look!

Wnt signaling pathway

The Wnt signaling pathways are a group of signal transduction pathways made of proteins that pass signals into a cell through cell surface receptors. Three Wnt signaling pathways have been characterized: the canonical Wnt pathway, the noncanonical planar cell polarity pathway and the noncanonical Wnt/calcium pathway. All three pathways are activated by binding a Wnt-protein ligand to a Frizzled family receptor, which passes the biological signal to the protein dishevelled inside the cell. The canonical Wnt pathway leads to regulation of gene transcription. The noncanonical planar cell polarity pathway regulates the cytoskeleton that is responsible for the shape of the cell. The noncanonical Wnt/calcium pathway regulates calcium inside the cell. Wnt signaling pathways use either nearby cell-cell communication (paracrine) or same-cell communication (autocrine). They are highly evolutionarily conserved in animals, which means they are similar across animal species from fruit flies to humans.
